MEC1011 Fall’05
Assignment 4
Due at the end of Week 3
Reference Chapter 2 Part Modeling 1 (pp 86-103)
Start a new project named after your username and located in
V:/MEC/1011/Fall_04/CADD/Assignment_4/Tx.
1.
Create a new part. Name it T.
2.
Edit sketch 1 and make a T shape. Constrain and Dimension the T to achieve a symmetrical
shape in ¼” increments; ie 1 ¼ x ¾ and so on. Fully constrain your sketch, using geometric
constraints make arms equal to stem width.
3.
Extrude the T using whole numbers. Save part as T and “save a copy as”
T_with_centerplanes.
4.
Close T and open T_with_centerplanes. Construct 2 work axes as shown.
5.
At their intersection place a work point and thru that work point add another work axis
(center axis) parallel to the extrusion.
6.
Add a work plane thru the center axis and parallel to the plane of symmetry.
7.
Add (2) work Points at opposite corners. Connect then with a Work Axis. Now using the
“on point” choice from the panel hole feature; add a hole thru the (2) work points.
8.
Saveas T_with_diagonal_hole
9.
Make a new part and using your work plane practice create a Loft. Save it as Loft.ipt
10.
Do the same for a Sweep.
11.
Make a simple extruded part and draft all faces with Face Draft. Save this as another file
called Face Draft.
12.
Make an Extruded and shelled shape. Add Ribs to the interior at regular intervals.
13.
Using Windows Explorer check your folder and make sure your files are all there. There
should be at least 6 .ipt’s, and 1 .ipj. If there aren’t see your instructor before leaving.
